The only instances of get_user_pages_remote() invocations which used the vmas parameter were for a single page which can instead simply look up the VMA directly. In particular:- - __update_ref_ctr() looked up the VMA but did nothing with it so we simply remove it. - __access_remote_vm() was already using vma_lookup() when the original lookup failed so by doing the lookup directly this also de-duplicates the code. This forms part of a broader set of patches intended to eliminate the vmas parameter altogether. Signed-off-by: Lorenzo Stoakes <lstoakes@xxxxxxxxx> ---
I guess we should never drop the mmap lock temporarily in these cases, so it's fine.
